I've been looking at trying out AppHub https://apphub.io/, which is comparable to CodePush. I'll have to try this.

As it is, both are definitely useful for better handling upgrade process with users. A couple drawbacks with mobile apps are that it's harder to hotfix errors, and you sometimes have to support older APIs for longer. With a web app, a user can visit the site and the entire app bundle can be downloaded after a cache bust.

As a team of web devs who love mobile, we definitely wanted to help bring as much of this kind of update experience to client apps as possible. I look forward to hearing any feedback you may have after giving us a try :)
